Speed range of the drive的意思|示意

Direct control of torque over the motor speed range is provided by the drive, which helps the motor and drive generate torque levels high enough to cycle the press back to ready position.

直接控制扭矩而不是电机转速范围，可以使得电机和变频器产生足够高的扭矩使得压机可以回复到原来的位置。

High torque to weight ratio, high efficiency and wide speed range should be the qualities possessed of by the motor drive systems in Electric Vehicles.

电动汽车中的电机驱动系统应该具有高转矩重量比、高效率以及宽广调速范围等特点。

Simulation results show that the EKF can give the accurate estimation of rotor speed and flux in all drive range, and the proposed control scheme processes the perfect dynamic and static performance.

仿真结果表明EKF可在整个调速范围内进行高精度的转速和磁链估计，控制系统具有优良的动态和稳态性能。
